Your Scarborough Insulation & Fireproofing Contractor

Scarborough's housing is some of the GTA's most diverse — Guildwood ravine bungalows, Agincourt sidesplits, Cliffside post-war stock, and waves of new-build infill. Northstar serves all of it, with a strong base in attic insulation upgrades.

Many Scarborough homes were built before R-40 attic code, and original fibreglass has often compressed to R-15 or less. Our blown-in cellulose and attic-spray-foam crews bring these homes up to R-60 in a single day for typical prices well under $2,500.

Scarborough tip

Scarborough Bluffs and Guildwood homes face stiff winter wind off Lake Ontario — attic R-60 with proper baffles delivers the biggest comfort jump.
